Benefits of technology

[0006]Aspects and embodiments of the present invention are directed to systems and methods of enhancing cardiopulmonary circulation in a subject. To increase venous blood flow toward the subject's heart during, for example, resuscitation efforts, controlled contractions of a muscle located remotely from the heart are induced. These controlled contractions increase the amount of blood in the venous blood flow toward the heart, enabling more blood to enter the subject's chest cavity, heart, and lungs during an expansion or relaxation phase of the heart.

Problems solved by technology

Cardiac arrest and other cardiac health ailments are a major cause of death worldwide.
These efforts have a limited success rate, and cardiac arrest, among other conditions, continues to claim the lives of victims.

Abstract

Systems and methods of enhancing cardiopulmonary circulation in a subject during resuscitation are provided. A signal is received responsive to an induced heart compression that is applied to the subject, for example during ventricular fibrillation, an asystolic condition, or cardiac arrest. Responsive to receipt of the signal, a muscle distal subject's heart is electrically stimulated to contract and expel blood into the venous blood flow toward a heart of the subject.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. 119(e) to U.S. Provisional Application Ser. No. 61 / 349,456 titled “Systems and Methods for Enhanced Venous Return Flow During Cardiac Event,” filed May 28, 2010, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of Invention[0003]The present invention is generally directed to cardiopulmonary circulation, and more specifically, to systems and methods that can enhance cardiopulmonary circulation during ventricular fibrillation, an asystolic condition, or sudden cardiac arrest.[0004]2. Discussion of Related Art[0005]Cardiac arrest and other cardiac health ailments are a major cause of death worldwide. Various resuscitation efforts aim to maintain the body's circulatory and respiratory systems during cardiac arrest in an attempt to save the life of the victim. These efforts have a limited success rate, and cardiac arrest, among other conditions,...
